My after doesn't work with my monitor

I have been having a problem in the preview of my after, where it had like freezing, and I didn't understand why this was happening, since previously it worked super well, now I discovered the problem by chance, but I still can't find a solution. 
I have two monitors, one of 144 Hz and the other of 60 Hz, obviously my main screen is the 144 which is the largest and I do all my work on it, by pure chance I opened the program on the 60 screen, and surprise. , it worked great without a single freeze, but when I moved the project to the other screen everything was horrible again. If this somehow helps a little more to find a solution, I'm looking forward to it because the truth is that I wouldn't want to work on such a small screen.
